Pemanfaatan Minyak Sawit Mentah / CPO Sebagai Bahan Baku Pembuatan Methyl Ester Sulfonate (MES)

Methyl Ester Sulfonate (MES) is an anionic surfactant that has the properties of renewable, clean and environment friendly. This study aims to determine the optimum conditions in producing MES. The raw materials used to make the MES is crude palm oil (CPO). CPO initially filter ed, then processed into methyl ester enzymatically, then treated by sulfonation with H 2 SO 4 concentration variation (7M, 9M, 11M) and temperature ( 85 O C, 95 O C ), and then carried out the methanolysis process using methanol and neuralize with NaOH. The results showed that the optimum condition is treated using sulfuric acid (H 2 SO 4 ) 9M  a t temperature of 85 0 C  generate yield of 49.99%, refractive index of 1.4454, the surface tension of 27.710 dyne / cm, interfacial tension of 31.50 dyne/cm , and emulsion stability at 100%.
